Gender reveal at baby shower

My fiancé and I can't decide if we want to tell anyone the gender or not. Mostly because we want to avoid getting just clothing at the shower, and more stuff that's on our registry (things we actually need. Plus, I'm sick to death of being hounded to want a girl. We figured we could have cupcakes with pink or blue filling at the shower and make it low key and deal with it then. Does this seem petty or stupid? I know it won't solve our "problems", but we're going to tell our families we didn't find out, and then bring out the cupcakes. Sorry if this is super ramble-y.
